If it is not just end-points you want to deal with then you’ll have to use modulo math:
Modding the index, i.e. Index % 2 = 0,1,0,1,0,1…etc. which then drives a switch which outputs the cuts for 0 (false) and 1 (true).
If it is more complex distributions then you’ll need to start using the Sample Curve and Set Position via some math expression.
Just a reminder: In future, please make sure you make what you want clear in the first post. Moving the goalposts will make people who want to help not want to help. Thanks.
Good luck.
